The solid-state reaction has the advantages such as simplicity, efficiency, and selectivity compared to the liquid-phase reaction in organic chemistry. However, the direct conversion of organic single crystals into a well-defined superstructure has remained challengeable. Here, we describe the formation of superstructure by the solid-state reaction from an organic single crystal. The superstructure of 5,5',5''-(1,3,5-triazine-2,4,6-triyl)triisophthalonitrile (TIPN) can be synthesized by stagnate cyclotrimerization of 1,3,5-tricyanobenzene (TCB) single crystals. The TIPN was confirmed by single crystal X-ray diffraction and visualized by transmission electron microscopy. The superstructure, TIPN, has hexagonally packed 1-dimensional (1-D) channels along the crystal axis. Moreover, interdigitated nitrile interactions in the TIPN crystal lattice has high thermal stability.
